DESIGN FEATURES

1.Cast Aluminum Heatsink – The cast aluminum heatsink of the Punch amplifier dissipates heat generated by the amplifier's circuitry. The inherent advantage of casting provides a 30% improvement of cooling over conventional extrusion heatsink designs.

2.End Caps – Interchangeable end caps conceal the wiring and input cables, giving the amplifier a clean “stealth” look.

3.Speaker Terminals – The heavy duty, gold-plated terminal block connectors (+ and –) will accept wire sizes from 8 AWG to 18 AWG. These gold-plated connectors are immune to corrosion that can cause signal deterioration.

4.Power Terminals – The power and ground connectors on the Punch amplifier are gold-plated and will accommodate up to 8 AWG wire maximizing the input current capability of the amplifier.

5.REM Terminal – This spade terminal is used for the auto power/ remote turn-on of the Punch amplifier.

6.RCA Input Jacks – The industry standard RCA jacks provide easy connections for signal level input. They are gold-plated to resist the signal degradation caused by corrosion.
